T0 all'whom it may concern:

Be it known that we, ROBERT TV. JAMIE- SON and Tnnononn MILLER, citizens of the United States, residing at New York city, in

the county of New York and State of New York, have invented new and useful Improvements in Clothes-Founders, of which the following is a specification.

This invention relates to clothes pounders and it consists in the novel feature hereinafter described and claimed.

In the accompanying drawing :Figure 1 is a vertical longitudinal section of the device. Fig. 2 is a bottom plan view. Fig. 3 is a detail perspective of the inner shell and its retainer drawn to a smaller scale.

The outer shell 5 and the inner shell 6 may be formed of any metal found suitable for the purpose, as zinc. These shells are formed substantially conical in contour in order to obtain a relatively high degree of air pressure in the upper portions of the shells when these are forced downwardly in a tub filled with water and clothes. It will be observed that the shells are arranged concentrically and the difference in surface area between the outer shell 5 and the inner shell 6, is relatively large, whereby to obtain the intervening chamber '7. The outer shell 6 is fitted to one end of a relatively long tube 8 which is surmounted by a handle 9. The inner shell 7 is provided adjacent to its base with a cross piece 10 which operates as a guard to prevent the entrance of the clothes into the said inner chamber and the possible wedging of the said clothes therein during the downward movement of the machine, and further acts as a ram for compressing the clothes during such downward move ment of the shell, and still further functions as a support for a rod 11 of wood or other suit-able material, which passes upwardly through the shell and the tube 8.

A. fastening device herein shown in the form of a cotter 12, is associated with the upper end of the rod 11 and is arranged so as to prevent the withdrawal of the rod through the tube and thereby co-acts with the said rod to have the latter function as a means for preventing undesired displacement of the inner shell with respect to the outer shell during the upward movement of the pounder under the conditions previously stated. The fastening device 12 is detachably connected to the rod 11, whereby to admit of removing the said rod with the parts connected thereto when the cleaning of the inner surface of the tube 8 and the said rod i found necessary.

A valve 13 herein shown in the form of a solid rubber washer, is fitted to a cylindrical extension lat at the upper end of the inner shell 6 and surrounds the rod 11. The cliameter of this valve is greater than that of the tube 8 and the lower end of the said tube is bent laterally and flattened as inclicated at 15, to provide a circular seat for the valve 13.

In the operation of the pounder the clothes to be washed are placed in a tub or other suitable receptacle with water and soa and the pounder is placed upon the clothes. The

operator by grasping the handle 9, forces the pounder downwardly. The presence of thematerial in the tub acting against the downward movement of the pounder, forces the inner shell upwardly until the valve 13 contacts with the valve seat 15, whereupon passage through the tube 8 is closed and the air entrapped in the chamber 7. As the downward movement of the pounder is continued the air in the chamber 7 will be forced through the clothes and will carry with it the dirt contained in the clothes. Upon upward movement of the pounder the air in the tube 8 assisted by the weight of the inner shell and the parts connected thereto, will effect the unseating of the valve 13 by moving the inner shell downwardly. The air from the tube 8 will now pass into the chamber 7 thus equalizing the pressure on the outer and inner surfaces of the outer shell whereupon the pounder may be readily moved upward. It will, of course, be understood that in the operation of washing the clothes the pounder will be reciprocated quite rapidly so that the air will be completely expelled from the inner shell 6 and the same filled with water after comparatively few reciprocations of the pounder.

What is claimed as new is:

In a clothes pounder, the combination of concentrically disposed outer and inner substantially cone-shaped imperforate shells, the said shells being arranged to move relatively to each other when the pounder is reciprooated in a receptacle containing Water In testimony whereof We aflix our signaand material to be Washed, an open-ended tures in presence of tWo Witnesses.
